OpenPGP Message Format

This document is maintained in order to publish all necessary information needed to develop interoperable applications based
on the OpenPGP format. It is not a step-by-step cookbook for writing an application. It describes only the format and methods
needed to read, check, generate, and write conforming packets crossing any network. It does not deal with storage and implementation
questions. It does, however, discuss implementation issues necessary to avoid security flaws. Open-PGP software uses a combination
of strong public-key and symmetric cryptography to provide security services for electronic communications and data storage.
These services include confidentiality, key management, authentication, and digital signatures. This document specifies the
message formats used in OpenPGP.
